To all whom it may concern: a

Be it known that I, FRANK O. BoneMsrsR, a citizen of the United States, residing at St. Charles, in the county. of St. Charles and 5 Stateof Missouri, have invented new and useful Improvements in Window-Sashes, of which the following is a specific tion.

This invention relates to wi dow sashes, and the object of the invention'is to provide lo a sash of a peculiar. construction whereby the glass or transparent material may be secured to the sash, and effectively retained in position thereon, without the use of putty and springs.

l5 With these objects in View the invention resides in the novel construction of sash frames and stri' s therefor, hereinafter fully described and c aimed. I

In the accompanying drawings,.Figure 1 2o is a' vertical transverse sectional view of a as modified form of construction, which caii be used to a better advantage for one glass in a sash.

in the accompanying drawings, and rcferring particularly to Fig. 1, the numeral l 30 designates the top bar of my improved sash and 2 the bottom bar thereof. The top, side and bottom bars are of a substantially same formation, and the mineral designating the construction of one of the bars may be taken 35 in connection with the opposite bar. .The

bars are of a construction similar to that commonly employed in the construction of an ordinarywindow frame, and are provided with a longitudinal glass receiving recess or -10 groove 3, terminating in a shoulder 4, of a width slightly less than. that of the thickness of the glass and upon which the. glass is adapted to rest. '1 is free end of the shoulder 4 is rovidcd with a vertical wall 5, l so provided with a shoulder 6, at

a right an le from its connection with the vertical wa l to the side of the bar. The distance between the glass receiving groove 3, and wall 5 approximately equals that of the 50 glass or transparent material, thus providing a step-like construction upon the bars. A retaining strip 6, is employed for securing the loss upon the up or groove. of the bar. his strip 6 is of a. height slightly less than the distance between the inclined wall 6 and the top o the bar. The strip 6 is provided with a longitudinal groove 7, upon its inner face, at a point approximately equaling that of the point of engagement with the lower edge of the glass. ofier flexibility to the strip and allow the face of the strip secure engagement with the glass. In order to more surely provide a tight con tact between the strip and the glass, the wall 5 is recessed as at 8 for a suitable distance from its-connection with the horizontal wall 4 ofthe upper recess. This construction, it will be seen, provides a space between the inner face of the strip 6 and the engaging face of the strip when the strip is positioned against the 'wall 5 of the bar, and. which will allow for the springing of the engaging face of the strip into contact with the glass when the screws or retaining elements are secured to the strip and the. bar. With this construction it will be seen that I have provided a substantially air and water tight connection for the effective securing of glass upon a window frame.

In order to secure several panes of glass upon a frame I have rovided a strip 9, provided with a pair of iongitudirml grooves 10 ositioned from each other so as to provide 1 caring faces 11 upon each side of the grooves, and a central portion 12 between the grooves. Directly opposite the strip .l is arranged a mullion 13, provided with a central rib 15, of a width less than the thickness of the glass. Upon each side of the rib 15 the strip is provided with bearing faces 14 adapted to contact with the glass u )011 the opposite sides thereof to that engaged by the bearing faces 11 of the mullion 9. When the retaining elements are inserted into the mullion and strip, it will bc readily seen that a tight connection between the two members is provided and that the glass is rctoined rigidly in position between the members.

In Fig. 2 I have illustrated av slight modification of my improvement. The bar H5, is of a similar COHSi-L'UCt-lOl'l and formation to that previously described, but the strip IT has its lower cdge beveled at a slightly greater angle than the bevel provided by the inclined surface 18 of the bar 16. The strip 17 is provided with a longitudinal groove near its point of en agcmcnt with the glass to allow the face of t is strip to hold more so curely to said glass or transparent motor oil,

and it will be seen, that when the strip is )ositioned upon the recess provided b the )ar '16, the retaining elements 19, may 0 insert- The object of this groove 7 is to ed at 'an angle, to force the inclined lower face of the strip upon the inclined portion of the bar and tends to draw the stripand the bar tightly into engagement with each other, and thus force the bearing securely against the glass.

' From the above description it will be seen that I have provided a simple and efiective manner of securing glass or transparent material to window frames, one by which the use of putty and springs is' dispensed. with, and which not only securely retains the glass upon'the frame but efiectively provides an air and water tight joint between the glass and the frame.

Having thus fully described the invention what is claimed as new is: I 1. A window sash comprising a frame provided with glass receiving recesses, retaining strip recesses, and recesses disposed between the first and second named recess, retaining strips disposed in the second named recesses having portions spaced from the third named recess to ofier flexibility tosaid strips, and means engaged with said frame and with said strip respectively for forcing the inner portilons of said strips into engagement with a ass. it g 2. A window sash having a frame provided with a glass receiving recess, a retaining strip recess and a recess provided between the glass and stri recesses, a retaining vstrip having'a longitu and means engaged with t e strip and with face of the strip inal channel u on its inner face, 1

the sash for holding a portion of the strip adjacent to said channel engaged with ,the glass,

said third named recess being rovided so that said strip will yield and tig tly bind at frame having a retaining strip recess and asmaller recess communicating with the glass receiving recess, and a flexible strip secured to the sash and engaging the glass.

4., A window'sash provided with glass receiving recesses, a pair of glasses disposed at their outer ed es in said recesses, means carried by the sas for looking engagement with the glasses adjacent to their outer edges, said glasses midway between the up er and lower edges of the sash being disposed in spaced relation, a mullion having a rib located between the glasses, a strip dis osed at the 0pposite sides of the glasses an provided with 4 a pair of longitudinal grooves, and fastening devices engaged with said strip and with said mullion, the rib of the mullion be s aeed from the strip to offer flexibility td f ti when said fastening devices are engaged with the said mullion.

In testimony whereof I aflix my signature in presence of two witnesses. I
